Why is Unova's Trainer Battle theme so underated? It was bold enough to be the first and only battle theme to implement the iconic opening theme of Red/Blue/Green into itself despite BW1 featuring, at the time, only new Pokemon for the most part of the game, and was the last Trainer Battle theme to still use same formula of rhythm and hooks shared by the first 5 Gens, before X/Y and S/M started using more untraditional sounding Trainer Battle themes.
